What Are the Symptoms of Poor Car Battery Contact?

[StChristian]

Automobile battery poor contact symptoms: unstable idling, battery damage, and damage to the generator. The following are the maintenance methods for automobile batteries: 1. Regularly check the electrolyte: The electrolyte level should always be kept between max and min. Check it once a month and supplement with distilled water (pure water) as needed, but never add acid. 2. Maintain normal voltage: When the battery voltage is insufficient and the lights are dim or the engine struggles to start, perform an external charge promptly. 3. Charge in time: Prevent the battery from being overcharged or chronically undercharged. Overcharging can cause active material to fall off, while undercharging can lead to plate sulfation. Ensure the regulator voltage is neither too high nor too low. 4. Regularly check the vent holes: During use, frequently check if the vent holes are clear to prevent battery deformation or explosion.
